I read a lot in bath (& in the loo). And I think I remember almost everything I have read at these 2 places, even better than in my study room. It's almost become a compulsion over the years. If I couldn't get a book or a magazine, I'd pick up the bottles and start reading the ingredients, where it was made and who bottled it etc.
I want to have a shelf in my bath where I place the books I like reading no matter whether I've read it before or whether old/new. My partner gets upset with this habit but I'm not the one to give it up!
